You can send your sample to us if you feel maybe it's impossible for your material, we can test it for you about drying and sterilization for free.

Advantages

Compared with conventional drying methods, which are heating from the outside to the inside by heat conduction, microwave show so-called volume heating with the following advantages:

1, temperature gradient directed towards the surface, i.e. temperatures inside are higher than outside, giving rise to a higher partial pressure that drives the evaporating liquid to the surface consequently, the superficial layer does not dry up completely and the surfaces remain permeable.

2, the liquid evaporating inside the product is emitted through the porous structure of the solid material’s macro-capillary system, resulting in a high drying velocity.

3, the heating of water and most organic solvents occurs selectively - due to the LDer dielectric losses of water as compared to the product to be dried.

5. Sterilization of beverage and the wine, the meat, the marine product, the roasted seeds and nuts, and etc.

6. Chemical material, medicine tablet

7. Powder for various material.

FAQ

1.What is microwave?

Microwaves are a form of electromagnetic energy with frequencies between 300 MHz and 300 GHz, generated by magnetrons under the combined force of an electric and a magnetic field perpendicular to each other.

2. What is the advantage of microwave equipment compare to traditional equipment?

Traditional is a surface drying and sterilization method, which is not only slow, but also non-uniform with the surfaces, edges and corners of mushrooms or fungus. The imperfect drying and sterilization will cause product rejections, waste energy and extend process time.

Microwave is a direct method of drying and sterilization. Energy is transferred through the material electro-magnetically, not as a thermal heat flux. Therefore, the effect of drying and sterilization is uniformity and process time is short.

Microwave mushrooms sterilizer and dryer could completely preserve the original color, fragrance, nutrition and other properties of spices.

3. How about safety?

Using scientific structure and patented suppression system, LD company industrial microwave drying machine no threat of electromagnetic radiation to the health and safety of equipment operators.
